Product details
Overview
74ABT241DB,118 from Nexperia is an octal 3-state buffer/line driver in 20-pin SSOP (SOT339-1) package, designed for high-speed bus interfacing with ±64mA/–32mA output drive, 2.6ns typical tPLH propagation delay at 5V, and operation across –40°C to +85°C. It supports dual independent output enables (1OE, 2OE), each controlling four outputs, and features power-up 3-state behavior for safe hot-insertion in backplane and motherboard applications.
For engineers reviewing the 74ABT241DB,118 datasheet, 74ABT241DB,118 pinout, 74ABT241DB,118 application, or 74ABT241DB,118 equivalent, key selection criteria include output drive strength, 3-state enable timing (tPZH ≤ 6.8ns), input/output capacitance (CIN = 3pF, COUT = 7pF), and compatibility with 5V TTL/CMOS logic families in industrial control and computing bus architectures.
Technical Context
The 74ABT241DB,118 implements a BiCMOS architecture delivering low static current (ICCZ = 50µA in 3-state) while maintaining high-speed performance. Its dual OE structure allows independent control of two 4-bit data paths-1Y0–1Y3 and 2Y0–2Y3-enabling flexible bus partitioning without external gating logic.
It supports full 5V operation (VCC = 4.5–5.5V), meets JEDEC Std 17 latch-up immunity (>500mA), and provides ESD protection per MIL-STD-883 (2000V HBM, 200V MM). Inputs remain disabled during 3-state mode, eliminating bus contention risks when outputs are tri-stated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - Ensures robust operation under noisy 5V rail conditions common in industrial computing systems. |
| tPLH / tPHL | 2.6ns / 2.7ns (typ, CL = 50pF) - Enables reliable 300+ MHz bus signaling in high-throughput memory or peripheral interfaces. |
| IOL / IOH | 64mA / –32mA - Drives heavy capacitive loads (e.g., >10 TTL inputs or long PCB traces) without signal degradation. |
| CIN / COUT | 3pF / 7pF - Minimizes switching noise and dynamic power consumption in dense board layouts. |
| tPZH / tPHZ | 3.2ns / 3.6ns (max) - Guarantees fast, deterministic bus arbitration timing for real-time control subsystems. |
| Operating Temp | –40°C to +85°C - Validated for use in extended-temperature industrial and automotive under-hood environments. |
| ESD Rating | 2000V HBM, 200V MM - Provides built-in handling robustness during automated assembly and field service. |
Pinout & Package
74ABT241DB,118 is housed in a 20-pin plastic SSOP Type II package (SOT339-1), 5.3 mm body width, with 0.65 mm lead pitch and gull-wing leads for surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enables - Independently disable Group 1 (1Y0–1Y3) or Group 2 (2Y0–2Y3) to isolate bus segments. |
| 2,4,6,8 | 1A0–1A3 | Data inputs for first 4-bit channel - Accept standard 5V TTL/CMOS logic levels with VIH ≥ 2.0V, VIL ≤ 0.8V. |
| 17,15,13,11 | 2A0–2A3 | Data inputs for second 4-bit channel - Electrically identical to 1A0–1A3; supports mirrored or asymmetric data routing. |
| 18,16,14,12 | 1Y0–1Y3 | 3-state outputs for first channel - High-impedance state (Z) when 1OE = HIGH; drives up to 64mA sink current. |
| 3,5,7,9 | 2Y0–2Y3 | 3-state outputs for second channel - Independent sourcing/sinking capability; no crosstalk with Group 1 outputs. |
| 10 | GND | Ground reference - Must be connected to system ground plane to ensure stable noise margin and EMI control. |
| 20 | VCC | Positive supply - Requires local 5V decoupling (e.g., 100nF ceramic) within 5 mm for AC performance integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Power-up 3-State | Outputs default to high-impedance at power-on - Prevents bus contention during system reset or cold start sequences. |
| Latch-up immunity | Exceeds 500mA per JEDEC Std 17 - Eliminates risk of destructive latch-up in high-noise industrial power environments. |
| Dual independent OE control | Enables selective activation of two 4-bit data paths - Reduces need for external multiplexers in modular I/O expansion designs. |
| Low input capacitance | 3pF typical - Minimizes loading on upstream drivers and preserves signal edge rates in multi-drop configurations. |
| High noise immunity | VIL = 0.8V, VIH = 2.0V - Provides 0.4V noise margin against ground bounce and supply ripple in mixed-signal boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT241DBR | TI version in same SOT339-1 package; identical pinout and AC specs, but ICCZ = 100µA (vs. 50µA) and slightly higher tPLH max (4.6ns vs. 4.1ns). | Same industrial bus buffering use case; minor impact on power budget in always-on systems. | Select SN74ABT241DBR only if TI's qualification documentation or supply chain alignment is required for OEM compliance. |
| 74LVT241DB,118 | Nexperia LVT variant: 3.3V-only supply (3.0–3.6V), lower drive (±32mA), faster tPLH (1.8ns typ), but incompatible with 5V systems. | Not suitable for 5V legacy infrastructure; intended for new 3.3V low-power designs where voltage scaling is acceptable. | Choose 74LVT241DB,118 only when migrating to 3.3V logic domains and reduced power is prioritized over backward compatibility. |
Compared with SN74ABT241DBR and 74LVT241DB,118, the 74ABT241DB,118 uniquely balances 5V tolerance, ultra-low ICCZ, and proven industrial temperature reliability-making it optimal for retrofitting legacy 5V systems requiring minimal redesign effort and long-term component availability.

FAQ
What is the maximum operating voltage for the 74ABT241DB,118?
The 74ABT241DB,118 has a recommended DC supply voltage range of 4.5V to 5.5V, with absolute maximum VCC rated at +7.0V. Operation outside the recommended range may compromise timing accuracy, output drive capability, or long-term reliability. The 74ABT241DB,118 is not rated for 3.3V-only operation and must be powered from a stable 5V rail.
Does the 74ABT241DB,118 support hot-swap or live insertion?
Yes-the 74ABT241DB,118 features power-up 3-state behavior, meaning all outputs default to high-impedance at power-on until valid enable signals are applied. This prevents bus contention during hot-plug events in backplane or modular systems. The 74ABT241DB,118 also includes input disable during 3-state mode, further enhancing system safety during live insertion.
How does the dual OE architecture of the 74ABT241DB,118 improve system design?
The 74ABT241DB,118 provides two independent output enables (1OE and 2OE), each controlling four outputs (1Y0–1Y3 and 2Y0–2Y3). This allows selective activation of data paths without external logic, reducing component count and PCB area in systems requiring segmented bus control-such as multi-slot I/O chassis or dual-memory bank addressing. The 74ABT241DB,118 eliminates need for additional gates or CPLDs in such topologies.
What thermal considerations apply to the 74ABT241DB,118 in continuous operation?
The 74ABT241DB,118 specifies a maximum junction temperature of 150°C. At full output drive (64mA per output), thermal dissipation must be managed via adequate copper pour, airflow, or derating. In typical 5V/25°C operation with partial loading, junction rise is <10°C above ambient. The 74ABT241DB,118 is qualified for –40°C to +85°C ambient operation, with thermal performance validated per JEDEC JESD51 standards.
Is the 74ABT241DB,118 pin-compatible with older 74-series buffers like the 74LS241?
No-the 74ABT241DB,118 uses a different pin configuration than the 74LS241. While both are octal 3-state buffers, the 74ABT241DB,118 places 1A0–1A3 on pins 2,4,6,8 and 2A0–2A3 on pins 17,15,13,11, whereas the 74LS241 assigns inputs and outputs differently. Direct replacement requires PCB layout revision. The 74ABT241DB,118 is pin-compatible only with other ABT241 variants in SSOP (e.g., 74ABT241DB,112).
